Corporation Bank — otp does not get generated and many other complaints

Corporation bank web login is really unusable.
My present complaint is:
- when i try to complete neft/rtgs transfer the otp doesnt get generated and sent to my registered mobile.
It works sometimes, but most of the times it doesnt work, particularly when you want to do any urgent transfer.

- the web center service is extremely poor (I will give a 0 rating if i could) - the web center never picks up the calls, and they dont answer emails. There is no way to reach them, and even the branch employees have a problem reaching the web center.
- there is a request i sent to the web center which has been pending for 10 months now and has not received a response or remediation.

There are also many other issues:
- they upgraded the software and locked all the old users. Since otp does not get generated and web center does not response, it was impossible to unlock the acccount.
- their software is really poor in terms o[censored]sability and predictability.
